摘要: |
本文对太湖水环境研究作了-个简单的回顾,指出了这几十年工作所取得的成就,如太湖进出污染物调查和水质评估,太湖水体光辐射观测与模拟等.结合国家有关太湖治理措施与方案,提出了“九五”工作应该着重在湖泊生态管理模型,水土界面营养物质交换及蓝藻水华爆发机制等领域.通过对当前国际上在这些领域中研究进展情况的回顾,特别介绍了在湖泊水动力学的观测、解释、模拟和应用方面,在湖泊藻类生长以及水华出现与湖泊光照条件、营养盐水平的关系方面,和湖泊营养盐内源释放的-些最新的进展.指出了太湖研究工作与国际上的差距所在.最后,对“九五”期间开展工作所取得的初步成果作了-简要的总结. |

Abstract: |
Taihu Lake is a large and shallow lake locatcd in the delta of the Changjiang River. It is an importment lake since it undertakes the drinking water supply,the transportation, sightseeing and culturing. In the last decade, this lake is suffering from the eutrophication caused by industrialization around the lake area. This paper attempts to summarize the research activities and conclusions in Taihu Lake in the past several decades. According to the current urgent requirements of the countermeasures to harness deterioration of lake environment suggested by the government, some key problems that should be addressed in the Ninth 5-ycar Plan are put forward,i.e. the lake management model which will be based on the hydrodynamic processes coupled with the diffusion and migration processes of nitrient and algae,the mcchanism of the occurrence of Cyanobacteria bloom, the release of nutrients from sediments. By the survey of literature in the international journals, a prospect about the relevant topics have been reviewed and the wantings have been revealed. Finally, the primary conclusions of the ongoing research projects have been summarized. |
